SIDE-HILL PLOW.

SPECIFICATION forming part of Letters Patent No. 405,489, dated June 18,1889.

Application filed March 27, 1889- Serial No. 304,953. (No model.)

To all whom it may concern.-

Be it known that I, FRIEDRICH KUNTZMAN, a citizen of the United States,residing at Troy, in the county of Madison and State of Illinois, haveinvented a new and useful Side-Hill Plow, of which the following is aspecification.

My invention relates to an improvement in side-hill plows; and itconsists in the peculiar construction and combination of devices, thatwill be more fully set forth hereinafter, and particularly pointed outin the claims.

I11 the accompanying drawings, Figure l is a perspective view of a plowembodying my improvements. Fig. 2 is a top plan view of the same, with aportion of the beam removed, so as to disclose the plowshare and thepivoted mold-board. Fig. 3 is a transverse sec tion through the share,and Fig. 4 is a longitudinal section of the plow.

Depending from the rear end of the beam Ais the standard B, to the lowerend of which is secured the forward-extending arm 0. The latter shouldbe preferably made of iron or steel, but the beam and standard maybemade of wood or any other suitable material. The front upper corner ofthe arm 0 is cut away and curved, as at D, and thereby the front end ofthe said arm is substantially wedgeshaped. In the extreme front end ofthe arm is a re-entering notch E. The usual handles F are attached tothe rear end of the beam, and are provided with the stay bar or rung G,and a clevis H is pivotally attached to the front end of the beam by abolt I, which passes through a vertical opening in the beam and throughopenings in the rearward-extending arms K of the clevis.

At a suitable distance from the front end of the beam is a verticalrectangular opening L, which extends entirely through the same, and inthe said opening is fitted the upper end or standard of a colter orcutter M, the latter havin g its lower end curved forward, as shown, andbeing sharpened on its front edge. Awedgeshaped key N is inserted in theopening L and bears against the standard of the colter, and therebyserves to secure the latterfirmly to the plow-beam.

The plowshare O is V-shaped, and is thereby provided withlaterally-extending wings P,

which project beyond opposite sides of the arm C. At the rear end of theplowshare, at the center of the same, is formed a rectangular loop orkeeper B, into which the wedgearranged under the colter or cutter withthe.

point of the latter almost or quite in contact with the share.

A vertical shaft S is journaled in a vertical opening in the plow-beamabove the share, and the lower end of the said shaft is journaled in acentral opening T near the rear side of the plowshare. To the said shaftat a suitable distance above the plowshare is rigidly secured a wing ormold-board U, which has its lower edge curved upward and outward, asshown, and has its upper edge substantially horizontal, At the upper endof the shaft S is a crank-arm V, and in the plowbeam at a suitabledistance in rear of the opening through which the shaft extends and nearthe sides of the said beam are a pair of vertical openings IV. A pin orstud X is adapted to be inserted in either of the said openings, and thearm V of the shaft is adapted to bear against the said pin,.so as tosecure the mold-board in an oblique position when extended from eitherside of the plowshare.

The operation of myinvention is as follows: The plowshare cuts arelatively broad furrow under the earth and the colter or cutter cutsthe said furrow longitudinally in its center. The mold-board must be soadjusted as to throw one half of the furrow downhill as it turns thefurrow over, and when the end of the furrow is reached the plow isturned, the share is inserted in the same furrow, and the mold-boardadjusted to the opposite side of the plowshare, and caused thereby'tothrow the remaining half of the furrow in the same direction as thefirst half. By shifting the position of the mold-board at each end ofeach furrow all the furrows may be thrown in the same direction, as willbe readily understood.

Having thus described my invention, I claim 1. The beam A, having thedepending standard B, provided with the forwardly-projecting arm 0,having the share 0 fitted thereupon,

in combination with the crank-rod S, journaled in the beam, and arm 0,and provided with the rearwardlvprojecting wing U, substantially asspecified.

2. A plow-beam A, having the standard B, and arm 0, the latter cut away,as at D, and

recessed, as at E, and the share 0, having keeper R, adapted to receivethe cut-away portion D, and having an opening vertically aligning withthe recess E, in combination with the crank-rod S, vertically journaledin the beam A, and terminating in the recess E, and having the wing U,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.
